Facebook canvas is a blank page

We think that the blank canvas page is probably because your SSL certificate is not trusted by Facebook. Going to the https version of your site, I get several warnings. The first screenshot is from Chrome, the second from Firefox.

Try to resolve this first, and see if fixes the issue.

When attempting to view it in Facebook now, we can see the following error in the console.

Refused to display 'curotrak.com/' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'.

You'll have to narrow down what's setting that value in the header - the website, your server, any security extensions (in Joomla or your server), etc.

Googling the error shows that other people have had the issue with Canvas apps for Facebook (regardless of using JFBConnect or not - salesforce.stackexchange.com/questions/1...ponse-header-of-exte

We're not saying you have to live without it. Melissa showed above that there is server configuration option that is specifically dis-allowing your site to be shown in an iFrame. That's not something that JFBConnect can get around.

With that said, I just tested again and the Page Tab is now showing a message about redirecting to the site and then I'm brought to your home page. I'm assuming you changed something.

Finally, for the Facebook Invites, if you remove the Secure Canvas URL and Canvas URLs from your app configuration, then received invitations will bring the user directly to your site instead of using the Canvas app. If you have an SSL certificate, JFBConnect will enable the canvas options, but you can disable that if you want.

I hope that helps explain,
